Antenna-embedded case for mobile communications terminal, method of manufacturing the same, and mobile communications terminal

Abstract

A method of manufacturing an antenna-embedded case for a mobile communications terminal includes providing an antenna pattern, forming a first injection-molded member covering one surface of the antenna pattern, and disposing the first injection-molded member, provided with the antenna pattern on one surface thereof, in a second mold with the antenna pattern disposed in a space inside the second mold, and injection-molding a second injection-molded member covering the other surface of the antenna pattern to embed the antenna pattern between the first injection-molded member and the second injection-molded member.

1. A method of manufacturing an antenna-embedded case for a mobile communications terminal, the method comprising:
 providing a three-dimensional metallic antenna pattern including first and second surfaces and an interconnection pin extending from the first surface; 
 forming a first injection-molded member including first and second surfaces and covering the first surface of the antenna pattern from which the interconnection pin extends; and 
 disposing the first injection-molded member, provided with the antenna pattern on the first surface thereof, in a second mold including a space with the antenna pattern disposed in the space, and injection-molding a second injection-molded member covering the second surface of the antenna pattern to embed the antenna pattern between the first injection-molded member and the second injection-molded member, wherein 
 the interconnection pin and the antenna pattern are formed in an integrated manner. 
 
     
     
       2. The method of  claim 1 , wherein the antenna pattern excluding the interconnection pin is formed into a flat type. 
     
     
       3. The method of  claim 2 , wherein the forming comprises injection-molding the first injection-molded member such that an open end of the interconnection pin is exposed to the second surface of the first injection-molded member. 
     
     
       4. The method of  claim 1 , further comprising processing the antenna pattern into a structure having a three-dimensional shape, before the forming. 
     
     
       5. The method of  claim 1 , wherein the forming comprises:
 inserting the antenna pattern in a first mold including a space having a shape of the first injection-molded member; and 
 injecting a molding material into the first mold and molding the first injection-molded member covering the first surface of the antenna pattern. 
 
     
     
       6. A mobile communications terminal comprising an antenna-embedded case manufactured according to the method of  claim 1 . 
     
     
       7. An antenna-embedded case for a mobile communications terminal, the antenna-embedded case comprising:
 a three-dimensional metallic antenna pattern including first and second surfaces and an interconnection pin extending from the first surface; 
 a first injection-molded member including first and second surfaces and covering the first surface of the antenna pattern from which the interconnection pin extends; and 
 a second injection-molded member injection-molded to cover the second surface of the antenna pattern such that the antenna pattern is embedded between the first injection-molded member and the second injection-molded member, wherein 
 the interconnection pin and the antenna pattern are formed in an integrated manner. 
 
     
     
       8. The antenna-embedded case of  claim 7 , wherein the antenna pattern excluding the interconnection pin is formed into a flat type. 
     
     
       9. The antenna-embedded case of  claim 7 , wherein the first injection-molded member and the second injection-molded member are formed of different materials. 
     
     
       10. The antenna-embedded case of  claim 9 , wherein the first injection-molded member includes a material for shielding electromagnetic waves.
